Essentially, up to 30% of the cost in heating and cooling your home is simply lost through the attic in many homes. Attic insulation is one of the most important and effective means to your homes capacity in retaining cool and heated air,making your home comfortable all year round.
Do I Have Enough Insulation? No matter what kind of insulation you currently have in your attic, one quick way to determine if you need more is to look across the span of your attic. If your insulation is just level with or below your attic trusses you should add more. It is important that the insulation be evenly distributed with no low spots; sometimes there is enough insulation in the middle of the attic and very little along the eaves.
How Much Insulation Should I Add? Insulation levels are specified by R-Value. R-Value is a measure of insulation’s ability to resist heat flow. The higher the R-Value, the better the thermal performance of the insulation. The recommended level for most attics is to insulate to R-38 to R-49 or about 10 to 16 inches, depending on insulation type.
Weighing both the pros and cons of insulation – whether it is fiberglass, cellulose or spray foam insulation – can be a great way to decide which the best choice for your home is. As with anything, if the positives outweigh the negatives, it is a good decision that pays dividends. The advantages of spray foam insulation are a list of strong attributes that can help make your choice a simple and easy one.
Although spray foam insulation does have an initial higher investment, the advantages that spray foam offers far outweigh the upfront cost. When you factor in the performance advantage of spray foam insulation that allows you to save on monthly heating and cooling bills every month, the return on investment makes up for the initial upfront investment. This is because spray foam fills all cracks and crevices where it is applied to limit air leakage which drives your heating and cooling equipment to work overtime to compensate for all that lost air. Also consider that spray foam insulation is not a do-it-yourself project. However, the advantage of a spray foam insulation installation is that you can ensure professional work done by an experienced and licensed contractor.
Some other advantages of spray foam insulation include the insulation’s ability to reduce the risk of ice damage in the cold winter months by keeping your attic/ roof at a constant temperature to help limit the chance of snow melting and refreezing on the eaves. Spray foam insulation also reduces the likelihood of mold due to the air barrier it creates upon application. Some other advantages of spray foam insulation include:
Open cell spray foam can create a quieter living space with its sound dampening qualities Indoor living environments can be enhanced due to the foam’s ability to limit the infiltration of allergens and pollutants Once cured, spray foam stays where it is sprayed without sagging or settling over time.
